Bullet Point Summary of the Podcast Episode
- New Obesity Measurement Data (Harvard/Mass General Study)
Harvard and Mass General propose adding waist circumference to BMI to better diagnose obesity.
Traditional BMI misses key factors like muscle mass and body composition.
Using the updated measure, Americans classified as obese jumps from ~43% to almost 69%.
This means 7 out of 10 U.S. adults would now qualify as having the disease of obesity.
Dave notes this validates many people who “feel” metabolically unwell despite a “normal” BMI.
Reinforces his claim that “most people should be talking to their doctors about GLP-1s.”
- New Oral Triple Agonist (Ascletis – ASC41/ASC? Molecule)
From Ascletis (A-S-C-L-E-T-I-S), developing an oral triple agonist targeting:
GLP-1
GIP
Glucagon
Similar in mechanism to retatrutide, expected around 2027.
Preclinical (animal) data show stunning results:
Oral bioavailability of 4.2%
9× higher than tirzepatide
30× higher than oral semaglutide
6× higher than oral retatrutide
57× greater drug exposure than oral retatrutide
Half-life ~56 hours
Stronger receptor activation than retatrutide in vitro
Suggests potential for the first powerful oral triple agonist—worth watching.
️ 3. Discussion of the Gray Market / TikTok Experience
Dave briefly recounts losing his TikTok account and landing in an algorithm filled with teenagers promoting gray-market “retatrutide.”
Expresses concern over unregulated peptide sales, especially to minors.
- Fractal Health’s New Data – Weight Maintenance After Stopping GLP-1s
New results from the Reveal One study (Fractal Health).
Participants: lost 24% of body weight on GLP-1s → stopped injections → got one Revita procedure.
At 6 months post-GLP-1 discontinuation:
Weight changed only 1.5% (vs. ~10% regain in typical off-drug trials)
HbA1c barely shifted
Safety profile clean
Suggests possible long-term weight maintenance without injections through gut mucosal re-lining.
Dave describes his own recent attempt to switch drugs and significant hunger return.
- Food Noise & Biologic Hunger
Dave discusses how stopping Mounjaro caused terrifying, primal hunger.
Describes the distinction between:
Food noise (brain-based thoughts)
Hunger signals (biological/animalistic)
Reinforces why many patients cannot maintain weight loss without support.
- Zepbound (Tirzepatide) Cash-Pay Price Reductions
Eli Lilly drops cash-pay vial pricing:
2.5 mg: $349 → $299
5 mg: $499 → $399
7.5–15 mg: $499 → $449
Community feedback (informal poll):
Most say still too high to leave compounded versions.
Many would switch to branded if price hit $200–$300.
